Maestro's computer has time of day, but as you say there is no panel display. (Unless you freeze the waterfall. Then you can see a snapshot of the current time.)

The time seems to have been set once at the Dell CPU's birth and then not locked to the real world afterward, unless your radio has the GPSDO option. With GPSDO, you get high quality UTC timing.

I imagine Flex is reluctant to commit programming resources to this function, since they'd have to provide ways to set the time, either manually, from the Internet (if available via NTP or similar), or from a local PC, if available. Not rocket science, but lots of fussing for a low priority feature, they'd say.

All that said, it would be an obvious addition to the user interface! Once you have it, you could have a QSO timer, a wake-up alarm, and all that stuff you expect on a Windows tablet.

A Windows computer (like the Maestro) is actually a pretty terrible clock compared to other devices. Without regular correction from an accurate source, the multitasking operating system gets flummoxed. The harder it's working the worse it gets.

Your cell phone is a much better source of clock time. Accurate time is one of the requirements to make the cellular network work.

IMNSHO, program resources should be devoted to better radio performance, not making a $1200 alarm clock.

I understand why some would need GPSDO but I don't at this time. I felt an Antenna Genius was money better spent. I don't need an atomic clock as I don't care if it's a few seconds incorrect. I don't have anyone that is requiring me to be synced to NNTP servers. If I do want to get the exact time I can look at my cell phone but if I'm using my Maestro I do not want to fumble around to find a wall clock or find my cell phone. I do want to know the general time ideally displayed near the top center and shuts off when any button, dial or know is touched, then turns back on a few seconds later.
